I'm a relative newbie and need some advice on how to program a machine.  I want to have a stepper motor power a feed roller.  Why a stepper?  High torque, very good speed control.  Basically running continuously would be fine.  is there a way to do this?  how about looping a command like g1 x5 so that it would keep feeding 5 inches of material (assuming proper calibration) into a cutter.  thanks for any input offered.  just want to get on with the project and get the machine built.

g01 x5. f20. (feed at 20 inch per min)
m47 (repeat program from start)
